CHART FOR THE SPINAL COLUMN.

Specification of Letters Patent.

Patented am as, rare.

To all whom it may concern Be it known that I, OAKLEY SMITH, a citizenof the United States, and a resident of Chicago, in the county of Cookand State of Illinois, have invented a new and useful Chart for theSpinal Column, of which the following is a specification.

In the examination and treatment of the spinal column it is extremelydesirable to have a simple and certain scheme for indicating thefindings for subsequent compari son. The indicating of the entire spineupon a single sheet or page would either involve the employment of asheet of an inconveniently large size to be easily handled, or, it thesheet were of convenient size, the chart would necessarily be of suchsmall size as to render it useless so far as indicating findings thereonwere concerned. It is, of course, possible and desirable to consider thevertebrae in groups, and a diagrammatic or schematic charting of suchgroups may be conveniently made upon separate pages of a note book ofconvenient size. Such a charting, however, would have the considerabledisadvantage of failing to show the often important and vital relationexisting betweenvertebrae of different groups.

The object of my present invention is to provide in book form and ofconvenient size a chart upon each page of which may be readily indicatedthe findings with relation to each vertebra in groups of convenient sizeand the relations between adjacent vertebrae of different groups.

I attain the above object by the design illustrated in the accompanyingdrawing which shows two pages of a note book prepared in accordance withmy invention.

Figure 1 is an illustration of a page of a note book embodying myinvention, and Fig. 2 is an illustration of a page adapted to succeedthe page as shown in Fig. 1.

I have found that the vertebrae may be conveniently considered andlisted in groups of five. Upon the pages I have drawn diagrammatic orschematic vertebrae, 1, con sisting of groups of rectangular blocks, 2,which are best adapted for receiving the notations which the doctor maydesire to make.

A group of five of the schematic vertebrae, 1, are arranged one aboveanother in the central portion, 3, or" the page, and above and below thegroup, 3, are provided two more schematic vertebrae, and 5, and 6 and 7,which belong respectively to the group appearing upon the preceding andsucceeding pages. In this manner there is ample provision for indicatingclearly, upon the same page, the relation of the vertebrae of the groupillustrated to the vertebrae of the ad jacent groups. In order to:l'ully secure the advantages which may follow from illustrating andconsidering the vertebrae in groups, I have made the grouping apparentby dividing the group proper appearing on a page from the vertebrae ofthe preceding and succeeding groups by the heavy lines, 8 and 9.

Having illustrated and described my invention, what I claim as new anddesire to secure by Letters Patent is 1. A spinal chart comprising adiagrammatic representation of a plurality of schematic vertebraearranged in groups to illustrate the comparative relation of thevertebrae of one group to its respective preceding and succeedinggroups, and each vertebral representation comprising a rectangular areaadapted to receive indicia for indicating findings for subsequentcomparison.

2. In a spinal chart a schematic representation of a plurality ofvertebra, said vertebrae arranged in groups to illustrate thecomparative relation of the vertebrae of one group to its respectivepreceding and succeeding group, each vertebral representation comprisinga plurality of separated conventional areas adapted to receive indiciafor indicating findings thereon for subsequent comparison, and eachrespective subsidiary group being divided from the principal group.

In testimony whereof I aflix my signature in the presence of twowitnesses.

OAKLEY SMITH.
